Fix cases of calls to `FillPSBT` returning `complete=true` when it's not
the case.
This can happen when some inputs have been signed but the transaction is
subsequently modified, e.g. in the context of PayJoins.
Also fixes a related bug where a finalized hex string is attempted to be
added during `walletprocesspsbt` but a CHECK_NONFATAL causes an abort.
Reported in #30077.

Now that the queueing of the VERSION messages has been moved out of
`InitializeNode`, there is no need to pass a mutable `CNode` reference any
more. With a const reference, trying to send messages in this method would
lead to a compile-time error, e.g.:
----------------------------------------------------------------------------------------------------------------------------------
...
net_processing.cpp: In member function ‘virtual void {anonymous}::PeerManagerImpl::InitializeNode(const CNode&, ServiceFlags)’:
net_processing.cpp:1683:21: error: binding reference of type ‘CNode&’ to ‘const CNode’ discards qualifiers

Initiating an outbound network connection currently involves the
following steps after the socket connection is established (see
`CConnman::OpenNetworkConnection` method):
1. set up node state
2. queue VERSION message
3. add new node to vector `m_nodes`
If we connect to ourself, it can happen that the sent VERSION message
(step 2) is received and processed locally *before* the node object
is added to the connection manager's `m_nodes` vector (step 3). In this
case, the self-connect remains undiscovered, as the detection doesn't
find the outbound peer in `m_nodes` yet (see `CConnman::CheckIncomingNonce`).
Fix this by swapping the order of 2. and 3., by taking the `PushNodeVersion`
call out of `InitializeNode` and doing that in the `SendMessages` method
instead, which is only called for `CNode` instances in `m_nodes`.
Thanks go to vasild, mzumsande, dergoegge and sipa for suggestions on
how to fix this.

A common issue that our fuzzers keep finding is that outpoints don't

The ipv4 and ipv6 seeds are updated from sipa's crawler, as outlined in contrib/seeds/README.md. The onion and i2p seeds are pulled from my node's addrman using `getrawaddrman` and then a connection was made to each node to retrieve the current service flags, block height, and user agent string before filtering through makeseeds.py. The CJDNS nodes were not updated as my node is not connected to that network.
makeseeds.py is also updated for more recent user agent strings as well as being able to handle i2p addresses.
Also updated the testnet seeds.

f3a612f9016fe1f59c73d6059274bea8025b8940 gui: guard accessing a nullptr 'clientModel' (furszy)
Pull request description:
Fixing #800.
During shutdown, already queue events dispatched from the backend such
'numConnectionsChanged' and 0networkActiveChanged' could try to access
the clientModel object, which might not exist because we manually delete
it inside 'BitcoinApplication::requestShutdown()'.
This happen because boost does not clears the queued events when they arise
concurrently with the signal disconnection (see https://www.boost.org/doc/libs/1_55_0/doc/html/signals2/thread-safety.html).
From the docs:
1) "Note that since we unlock the connection's mutex before executing its associated slot, it is possible a slot will still be executing after it has been disconnected by a [connection::disconnect](https://www.boost.org/doc/libs/1_55_0/doc/html/boost/signals2/connection.html#idp89761576-bb)(), if the disconnect was called concurrently with signal invocation."
2) "The fact that concurrent signal invocations use the same combiner object means you need to insure any custom combiner you write is thread-safe"
So, we need to guard `clientModel` before accessing it at the handler side.

Pull request description:
This replaces #28674, #29036, and #29057. Now ready for testing and review.
Replaces platform-specific endian and byteswap functions. This is especially useful for kernel, as it means that our deep serialization code no longer requires bitcoin-config.h.
I apologize for the size of the last commit, but it's hard to avoid making those changes at once.
All platforms now use our internal functions rather than libc or platform-specific ones, with the exception of MSVC.
Sadly, benchmarking showed that not all compilers are capable of detecting and optimizing byteswap functions, so compiler builtins are instead used where possible. However, they're now detected via macros rather than autoconf checks.
This[ matches how libc++ implements std::byteswap for c++23](https://github.com/llvm/llvm-project/blob/main/libcxx/include/__bit/byteswap.h#L26).
I suggest we move/rename `compat/endian.h`, but I left that out of this PR to avoid bikeshedding.
#29057 pointed out some irregularities in benchmarks. After messing with various compilers and configs for a few weeks with these changes, I'm of the opinion that we can't win on every platform every time, so we should take the code that makes sense going forward. That said, if any real-world slowdowns are caused here, we should obviously investigate.

2. The value wasn't forwarded to libsecp as a user might have reasonably expected.
3. We now have the DISABLE_OPTIMIZED_SHA256 define which is what disable-asm actually did in practice.
If there is any desire, we can hook DISABLE_OPTIMIZED_SHA256 up to a new configure option that actually does what it says.
Additionally, this is one of the last (THE last?) remaining uses of autoconf defines in our crypto code. As such it seems like low-hanging fruit.

6ee3997d03e456655e3c44abf1e15270c423ed41 test: removes unnecessary check from validation_tests (Sergi Delgado Segura)
Pull request description:
An unnecessary check was added to the block mutation tests in #29412 where IsBlockMutated is returning true for the invalid reasons: we try to check mutation via transaction duplication, but the merkle root is not updated before the check, therefore the check fails because the provided root and the computed root differ, but not because the block contains the same transaction twice.
Notice that a proper check to test the duplication case is added a few lines later, so this check is just meaningless and can be removed. Check https://github.com/bitcoin/bitcoin/pull/29412#discussion_r1506490281 for context.

367bb7a80cc71130995672c853d4a6e0134721d6 wallet: Avoid updating `ReserveDestination::nIndex` when `GetReservedDestination` fails (UdjinM6)
Pull request description:
I think the expected behaviour of `getrawchangeaddress` and `getnewaddress` RPCs is that their failure should not affect keypool in any way. At least that's how legacy wallets work, you can confirm this behaviour by running `wallet_keypool.py --legacy-wallet` on master with e073f1dfda7a2a2cb2be9fe2a1d576f122596021 applied on top. However running `wallet_keypool.py --descriptors` on the same commit results in the following failure:
```
File "/path/to/bitcoin/test/functional/test_framework/test_framework.py", line 131, in main
self.run_test()
File "/path/to/bitcoin/test/functional/wallet_keypool.py", line 114, in run_test
assert_equal(kp_size_before, kp_size_after)
File "/path/to/bitcoin/test/functional/test_framework/util.py", line 57, in assert_equal
raise AssertionError("not(%s)" % " == ".join(str(arg) for arg in (thing1, thing2) + args))
AssertionError: not([18, 24] == [19, 24])
```
This happens because we pass `nIndex` (which is a class member) into `GetReservedDestination` and since it's passed by reference we get an updated value back, so `nIndex` won't be equal `-1` anymore, no matter if the function failed or succeeded. This means that `ReturnDestination` (called by dtor of `ReserveDestination`) will try to return something we did not actually reserve.
The fix is to simply use a temporary variable instead of a class member and only update `nIndex` when `op_address` actually has value, basically do it the same way we do for other class members (`address` and `fInternal`) already.

Pull request description:
This PR proposes to check for mutated blocks early as a defense-in-depth mitigation against attacks leveraging mutated blocks.
We introduce `IsBlockMutated` which catches all known forms of block malleation and use it to do an early mutation check whenever we receive a `block` message.
We have observed attacks that abused mutated blocks in the past, which could have been prevented by simply not processing mutated blocks (e.g. https://github.com/bitcoin/bitcoin/pull/27608 for which a regression test is included in this PR).
